conduit were not ink duits these Walls extend parallel and at anangle totheadjacent Wal portions, and are spaced .apart a distance equal totheWidth of the conduit at the longitudinally and at thetransversely-extending portions thereof. The length of the diagonalconnecting portions 13 is such that the Walls ofthe1longitudinally-extending portion 11 of each conduit at the point atwhich it bridges thecorrugation of the adjacent conduit is in perfectalinement with the Walls of each alternate extending portion of saidlast-mem tioned conduit, thus greatlyv strengthening the construction asa Whole, eliminating the right-angle turns in the co/nduits, andfacllitating the flow of fluid therethrpugh.

For spacing the wall plates the proper dis' tance apart, I preferablyprovide a Wire 16 bent to the desired form and of any suitable shape,as, for instance, square in crosssection. One of the plates, as plate15, is of somewhat greater length thanthe opposite' plate`14, and .thislonger plate is bent to extend across to the outer surface 17 of theWire 16 and to form an mWardly-directed flange 18 in engagement with theplate 14,

as is clearly illustrated in Fig. 3. The Wire at the intersection ofthelongitudinally-extending portion and the transversely-extending portionis` of reduced cross section, so

' that the longitudinally-extending portions present straight verticalcolumns,.the diagonal meeting line being largely concealed by the solderwhich is applied `to secure the parts together. Y At a point closelyadjacent the wire 16 the Wall forming the inner surface of the.corrugation is bent to form the diagonal inner wall'of the connecting-portion 13 of the conduit. so that the flow of the fluid `throughtheconduit is unrestricted, but' this diagonal Wall is practicallyinvisible from the outer surface of the cooler and does not detract fromthe.straight column eiect produced by the successive longitudinally--extending portions. y

Preferably the walls forming the conduit are parallel at all points, butit is not essential that they extend perfectly straight. In Fig. 4, thelongitudinally-extending-portion 11* is formed of parallel Walls, butthese parallel -walls are each curved not only to increase the radiatingsurface, but also to increase the strength of the apparatus and toprevent the adjacent Walls from collapsing under excessive strain.Identically the same spacing Wires are employed in connection with theform illustrated in Fig. 4 as those illustrated in the lother figures.In each case, the spacing strips or wires have straightlongitudinally-extending portions and vstraight transversely-extendingportions at the intersection of A'which there is a right angle on theinner side and abeveled or flattened surface on the outerside. iWherethe lcngitudinallyfextending;\fpgijtons" of each corrugation are alsocorrugated, these vcorrugationsextend only to the spacing strips and arepractically invisible from the front side of Ithe cooler. In each casethe straight column effect is produced and the`union ofv theseveralfco'nduits and their lines of interf j section are concealed bythe solder.

Having, thus described my invention. I claim as new and desire to secureby Letters Patent: i
